THRASHlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 245,791, dated August16, 1881.

Application filed January 31, 1881. (No model.)

To all whom it may concern:

Be it known that we, RILEY H. OOON and VVILLIAM H. GooN, of Oneida Lake,in the county of Madison and State of New York, have invented certainnew and useful Improvements in Thrashing-Machines; and we do herebydeclare that the following is a full, clear, and exact description ofthe invention, which will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, which form a part of this specification.

Figure 1 is a longitudinal vertical sectional view, and Fig. 2 is adetail view, in perspective, of the operating mechanism.

Similar letters of reference indicate corresponding parts in bothfigures.

This invention relates to thrashin g-machines; and it consists incertain improvements in the construction of the same, which will behereinafter fully described, and particularly pointed out in the claim.

In the drawings hereto annexed, A represents the frame of the machine,upon the sill B of which boxes or bearings O are provided for a doublecrank-shaft, D, the cranks E E of which are located closely adjoiningthe sides of the frame. The shaft D is provided with a drum orband-wheel, F, to which the motive power is applied.

G is ashaft, boxed or journaled in the sides of the frame, above and inrear of the shaft D. Shaft G is provided with a single central crank, H;and upon its ends, inside the framejare keyed or otherwise secured twotriangular plates or levers, I I, provided upon their inner faces, belowthe shaft G, with wrist-pins J. Pitmen K connect the cranks E of shaft Dwith the lower ends or corners of the plates I, to which a reciprocatingmotion is thus imparted when the machine is operated.

The separator or straw-carrier consists of two parts or sections, L M,the front one of which, L, is suspended by its front end, by means ofrods N, under the concave O of the cylinder 1?, from which it receivesthe grain and straw in the usual manner. The rear end of section L ispivoted to the upper corners of the plates I, which impart to it arearward and upward throw, thus separating the grain, which drops uponthe grain-table, from the straw,which passes over the fingers Q,arranged upon the rear end of section L, and drops upon the section M.The front end of the latter is pivoted to the front corners of theplates I, and its rear end is suspended by rods R, at the tail end ofthe machine. The upward and rearward throw imparted to section M by'thelevers or plates I separates the straw from the remaining grain, andfinally drops it upon the ground or upon the stacker, as the case maybe.

The front end of the grain-table S is supported upon pivoted rods orcranks T, and its rear end is pivoted to the wrist-pins J of the platesI, which give the said table a short upward and rearward throw, whichcarries the grain and chaff to the sieves or riddles U. In thearrangement of the latter and of the fan V, table or conveyer W, (whichcarries the waste grain from the tail end of the machine back to theriddles,) and of the beateror picker X, rear of the cylinder, no noveltyis herein claimed.

From the foregoing description, taken in connection with the drawingshereto annexed, the operation and advantages of our invention will bereadily understood. It will be seen that the sections L and M of theseparator move in the same direction at the same time, thus causingthelatter to receive the overflow from the former, and complete theoperation of separating the grain in a more thorough and satisfactorymanner than can be done where a single separator or straw-carrier isemployed. At the same time no increase of n10- tive power is demanded,both sections being actuated by the plates or levers I I,npon which theycounterbalance each other, as shown. Through the same medium of theplates I I the grain-tables or conveyers S and W are alsooperated, theformer being pivoted to the wrist-pins J, and the latter beingconnected, by means of a bent rod or pitman, Y, to the crank H of theshaft G, upon which the said plates I are keyed or otherwise secured, asabove stated.

In testimony that we claim the foregoing as In our own weliave heretoaffixed our signatures in presence of two witnesses.
